PROBLEM: Endometriosis is a chronic inflammatory disease associated with an impairment in immune response. Disorders in the peritoneal fluid and ectopic endometrium macrophage populations and their secretory products create a specific micro…

PROBLEM: The diagnosis of endometriosis, a prevalent chronic disease with a strong inflammatory component, is usually delayed due to the lack of noninvasive diagnostic tests. Purinergic signaling, a key cell pathway, is altered in many infl…

PROBLEM: The level of CCL19 increased in the peritoneal fluid of women with endometriosis, but the precise mechanism of CCL19/CCR7 in the pathogenesis of endometriosis remains unknown. METHODS: ELISA and immunohistochemistry were performed…

PROBLEM: The relationship between hepatitis B (HBV) infection in infertile couples seeking in vitro fertilization (IVF) treatment and infertility causes is unknown. METHODS OF STUDY: A total of 831 infertile couples attending our unit seek…

PROBLEM: How does hypoxia-mediated downregulation of dual-specificity phosphatase-2 (DUSP2) promote the development of endometriotic lesions? METHOD OF STUDY: The levels of IL-6 and DUSP2 were assessed in eutopic stromal cells with DUSP2 k…

PROBLEM: Inflammation is a key process in the establishment and progression of endometriosis. Resistin, an adipocytokine, has biological properties linked to immunologic functions, but its role in endometriosis is unclear. METHOD OF STUDY:…

PROBLEM: How is the role of inhibitor of apoptosis proteins (IAPs) in the development of murine endometriosis lesions? METHOD OF STUDY: BALB/c female mice (n = 36) were used for the murine endometriosis model. Endometriotic lesions were su…

PROBLEM: Is lipopolysaccharide (LPS) involved in the development of endometriosis? METHOD OF STUDY: BALB/c mice (n=69) were used for the murine endometriosis model. Mice with surgically induced endometriosis were injected with LPS intraper…

Endometriosis is a chronic inflammatory disease characterized by the elevation of proinflammatory cytokines, such as IL-6, in the peritoneal fluid. However, the precise mechanism of the highly elevated IL-6 levels in ectopic milieu remains …

PROBLEM: The role of extracellular signal-regulated kinase (ERK)1/2-mediated angiogenesis during endometriotic nidation is unknown. We posit that ERK1/2-induced angioblast differentiation and proliferation promotes ectopic endometrial angio…

OBJECTIVE: We investigated α-7 nAchR expression in human peritoneal macrophages and examined whether activation of nAchR might be a new therapy for endometriosis. MATERIALS AND METHODS: Human peritoneal fluid mononuclear cells (PFMC) were …

Thymic stromal lymphopoietin (TSLP) is produced mainly by epithelial cells and was originally found to stimulate the growth and activation of B cells, but it is now shown to function on both hematopoietic and non-hematopoietic cell lineages…

PROBLEM: Chemokines have been reported to play a sovereign role in the establishment and progression of endometriosis. Fractalkine is a chemokine that is upregulated in many inflammatory diseases including endometriosis. Fractalkine functio…

PROBLEM: Uterine natural killer (uNK) cells play a significant role in successful human pregnancy. Having previously demonstrated uNK cell progenitors in human endometrium, we hypothesized that abnormal uNK cell maturation contributes to in…

PROBLEM: Neutrophils are known to be accumulated in endometriosis; however, direct evidence of the impact of neutrophils in the development of endometriosis was lacking. To clarify the importance of neutrophils, we examined the effect of ne…

PROBLEM: The human endometrium periodically breaks down and regenerates. As platelets have been reported to contribute to the tissue remodeling process, we examined the possible involvement of platelets in endometrial regeneration. METHOD …

The steroid hormone progesterone (P), acting via the progesterone receptor (PR) isoforms, PR-A and PR-B, exerts a profound influence on uterine functions during early gestation. In recent years, chromatin immunoprecipitation-sequencing in c…

PROBLEM: Endometriosis is an estrogen-dependent inflammatory disease. Progestins are a first-line treatment for endometriosis via activation of pituitary progesterone receptors and suppression of systemic estrogen: a less than optimal treat…

PROBLEM: Resistance to apoptosis, together with inflammatory and invasive activity, contributes to the pathogenesis of endometriosis; therefore, approaches that can safely enhance apoptosis in endometriotic tissue are highly sought after as…

Endometriosis is a chronic inflammatory disease characterized by the growth of endometrial glands and stroma outside of the uterus. The disease affects approximately 10-15% of women of reproductive age and presents with clinical symptoms of…

PROBLEM: We aimed to evaluate modulatory effects of vitamin D3 on endometriosis-related features of endometriotic stromal cells. METHOD OF STUDY: The effect of vitamin D3 on adhesion, invasion, proliferation, apoptosis, cytokine production…

PROBLEM: Inflammation is an essential process in the pathogenesis of endometriosis. METHOD OF STUDY: Serum and peritoneal fluid (PF) samples were collected from women with endometriosis (n = 31) and women without endometriosis (n = 48). Ch…

PROBLEM: Chlamydia trachomatis (CT) is the leading sexually transmitted bacterial infection in humans and is associated with reproductive tract damage. However, little is known about the involvement and regulation of microRNAs (miRs) in gen…

Endometriosis affects more than 10% of women, causing significant pain and morbidity. It is also a significant cause of infertility. The aetiology of the disease remains an enigma, and the mechanisms responsible for the associated infertili…

PROBLEM: The proportion of CD4+ T lymphocytes, Th1, Th2, Th17, and regulatory T cells in endometriosis lesions and peripheral blood are not known. METHOD OF STUDY: Lymphocytes were isolated from endometriosis lesions (n = 10) and endometri…
